This invention relates to an auxiliary fuel oil heating system,particularly adapted'to beused as a system-for use on boarol ship orland for providingmeans to .insure a supply of. hot oil to any mainsteam generator when all conditions are in the state of `low temperatureand no otherl suitable means exist for raising the temperature of fueloil to the necessary degree in Vorder to venable the same toy belighted. at ya burnerl beneath theymain boiler or. to be lighted atburners beneath a plurality of boilers.

The auxiliary Vfuel oil heating system of this invention contemplatesthe employment of an auxiliary heater consisting of a small boilerprovided with the usual fittings, but containing in thesteamvand waterspace a coil or series of coils in which oil is inducted by means of apump, and which oil ,ontaking up the temperature of the .steam andvwater in which it is immersed,is 'fed by suitable means, such as apump,.toa main burner. or series of main burners, through manifolds in acondition in which it can be burned. l In first starting up theauxiliary oil heating system the auxiliary heater is heated first by asmall hand kerosene or light oil lamp, but after sufficient temperaturehas been imparted to the fuel oil in the coil and l oil line to theburners, the fuel oillitself can be burnediunder the auxiliary heaterproviding thereby a constant burner which is keptin use until thestarting up of themain boiler has been Vaccomplished at which time theoperation of the whole yauxiliary heating system is discontinued.

VThe invention consists in an auxiliary fuel oil heating system such asdescribed in the following specification and particularly as `pointedout in the claims.

Referring to the drawings: i Figure 1 is a diagrammatic plan of myimproved auxiliary fuel oil heating system.

10a66d `b6nea6h the man boilers and which operate in a manner wellAknown, to those skilled inthe Aart. 9 is an oil pump, 10 is a` fueloilstoragetank, 11 is a strainer, 12 is an air vessel, 13 is a steampressure gauge, 14 is a thermometer,'15 and 16 are mani.- folds, 17 is acoil through which the loil passes in being heated, the lower or inletend 18 of the coil terminates infa pipe 19 which extends verticallyupward throughthe interior of the coil and out through the, top 4 Thepipe 19 is connected by a union 2O to a valve 21 and said valve isconnected by pipes. 22, A23 and ,24`to the oil pump 9. The oil ypump 9is v connected by a pipe 25 to the strainer 11 .and said strainer isconnected by a pipe 27 and 36 are 'controlled by valvesv 37, 38 and 39respectively. The manifold 16"is` 'connectedby pipes40, 41 and 42 to thepipe25,

these pipes`f40, 41 and 42 constituting al recirculating line. A valve43 is provided inV the pipe 40 whereby the recirculation line may beopened or closed. An` auxiliary burner 44 is provided for the auxiliaryyboiler 5 andt-his auxiliary burneris connected by pipes 45` and`46toythe pipe 31. A `valve 47 is provided in the pipe 45 whereby `the burnerv43 may be connected [with or ldisconnected from the 'pipe 31. Water issupplied to the auxiliary boiler'5 through the pipe 48 controlled by u avalve 50.` yA branch pipe 51 isconnected at one end thereofthrough thetop of the boiler withthe steam space of the boiler Vand kthis pipe isprovided with a valve 52. Whenp desired, the vpipe 51 `which constitutesan arm, can kbe swung from thepposition illustrated in fulllines, Figs.3and 4, to the position illustrated in dotted lines, and cou# pled` tothe `upperend ofthe pipe,19,and then uponopenin'g the valve5`2,steamfcan be `blown through the pipe 19,` the .coil 17 and thepipes andy fixtures connected therewith.V The boiler 5 is provided with'ytheusual wellsknown gauge -glass.53 and tit# l lo tings '54. The pump 9 maybe.. operated by steam from the auxiliary boiler 5 conveyed theretothrough pipes 55 and 56,'the ex` haust steam being conveyed awayfrom'tlie. pump by a pipey 57,4or anypother well-known` power means maybe provided to operate said pump. A valve 58 is provided inthe pipe 55to control the admission of steam to the pump.V r1`he manif-old15 isprovided with a waste pipe 59 which is provided with a valve 60 and themanifold 16 is 'provided withfa waste pipe 61, controlled by a valve62;, y f

The general operation kof the apparatus hereinbefore specificallydescribed is asv follows z-Assuming the entire' system to be cold andthat it is ydesired to generate steam in the main boilers, or yany 'ofthem, the auxiliary boiler 5 has water therein in which a coil17 isimmersed. -The coil 17 yis supplied Vwith oil'from the fuel storage tank'by means of the pump 9 which draws' the oil from the storage supplytank through the pipe 27, strainer 11 and pipe 25 and forces-it throughthepipes 24, 23, 22 and 19 -to they bottom of the coil 17, thisconstituting'the oil supply.v The water in the boiler is at first heatedby'means of a'hand lamp .and when 'the water in the boiler` 5 'becomessufliciently heated to produce steam and lsufiicient pressure and heatto raise the temperaturelin the coil 17 toabout 240, then the oil iiisaid coil1 passes from thegcoil through the pipe 28 to the manifold 15and from the manifold through pipes 31, 32 and 33 to the'manifold 16.From the bis manifold 16 the oil passes to the burners 6, 7 and 8 underthe main boilers, or to any one of them, thefpassage of oil through thepipes 34, 35 and 36Lto the burners 6, 7V and v8 respectively beingcontrolled by the valves 37, 38 and39 respectively in the manifold 16 ithe coil 17 through vthe manifolds 15 and 16 and the pipes connectedtherewith before it arrivesat a temperature of 240, and in such Acasesif the, oil is not sufficiently heated for the purpose of burning freelyunder the boilers, it is recirculat'ed by vclosing the valves 37, 38.and 39,l opening ,the valve 43 andallowing the oil to circulate throughthe vpipes 40, 41, 42 and 25 through the 4.pump

9 and from the pump through the pipes 22,

23 and 24 back tothe coil 17.A This 'recirf culating of the oil may becontinued as long y as maybe desired.

As soon as the water-and'steam have been "sufficiently heated to startthe roil ini circulation as hereinbefore'describedfthen .the hand burnermaybe replaced by the vburner 44 which is suplied with oilthrough lthepipes 45 andy 46 from'the pipe 31, the Voil being turned on to or oil'from the burner 44 by means of the -.valve"47. The pump is v.If desired,the oil may be circulated from' operated by steam from the yauxiliaryVboiler supplied thereto by pipes and 56 governed v by the valve 58.

In addition to using the steam for operating the pump 9 and for'heatingthe oil, the system of piping hereinbefore described iny' lcludingk thecoil maybe blown out by the steam andk this is accomplished by swingyingthe pipe arm 51y from the position illus- Vtrated in full'lines, Figs. 3and 4,(to that will also drive the oil through thecoil 17,

pipe 28,inanifold 15, pipesSO, 31,' y32 and 33 out of the manifold16fandpipes leading therefrom to the mainburners.` The steam maybeutilized .to drive the oil .out of the pipes 40, 41, and 42, and, infact, by'means of the steam and the connection 51 from the vboiler tothe oil'piping system the oil can` be driven outof the entire oil pipingsystem strainer. 4 1I claim: c
